Dynamically update ContextFlyout TrayMenu with icons

[gondwanasoft]

I want to build a WinUI NotifyIcon's context menu in code when my app runs — and I'd like for the menu to be able to display icons.

If I use the default ContextMenuMode, I can build the menu but I can't display icons (a Win32 limitation?).

If I use ContextMenuMode="SecondWindow", I can probably display icons (untested) but I don't seem to be able to access the menu to change it in code. I assume that I need to access the SecondWindow's menu, but I don't know how to do that. It might even be private.

If anyone knows how to dynamically populate a context menu with icons, please advise!
